| Abstract: | Point to QH-200 grates which amounted in motion Lab of our department, the paper offered the four times the frequency of circuit made of four integrated type monostable circuit which can improve the accuracy of grate. The article introduced the design principle and the diagram of hardware circuit. At the same time, for check the effect of the circuit, offered the program for two phases square-wave signal generator, which was made up of 89C51 controller. |
